DiscretizePDE::femdpop

Details

  • This message is generated in the case that the finite element discretization failed.
  • In case a solution is returned by the solver, it is not to be trusted, as some part of the equations failed to be discretized.
  • The various forms of the message indicate in which component the failure occurred.

Examples

In the following case, there is a transition from the real to the complex plane:

One possible workaround is to add a 0 complex component to the equation, such that the solver works in the complex plane:

An alternative in this case is to specify a complex-valued InitialSeeding:

Note there is a small complex part of the solution:

This message can indicate that an overflow did occur:

This message can indicate numbers with a different precision than MachinePrecision numbers were generated:
